<p>The <a class="link" href="NMSettingIP4Config.html" title="NMSettingIP4Config"><span class="type">NMSettingIP4Config</span></a> object is a <a class="link" href="NMSetting.html" title="NMSetting"><span class="type">NMSetting</span></a> subclass that describes
properties related to IPv4 addressing, routing, and Domain Name Service.</p>
<p><a class="link" href="NMSettingIP4Config.html" title="NMSettingIP4Config"><span class="type">NMSettingIP4Config</span></a> has few properties or methods of its own; it inherits
almost everything from <a class="link" href="NMSettingIPConfig.html" title="NMSettingIPConfig"><span class="type">NMSettingIPConfig</span></a>.</p>
<p>NetworkManager supports 5 values for the <span class="type">“method”</span> property
for IPv4.  If "auto" is specified then the appropriate automatic method
(DHCP, PPP, etc) is used for the interface and most other properties can be
left unset.  If "link-local" is specified, then a link-local address in the
169.254/16 range will be assigned to the interface.  If "manual" is
specified, static IP addressing is used and at least one IP address must be
given in the "addresses" property.  If "shared" is specified (indicating that
this connection will provide network access to other computers) then the
interface is assigned an address in the 10.42.x.1/24 range and a DHCP and
forwarding DNS server are started, and the interface is NAT-ed to the current
default network connection.  "disabled" means IPv4 will not be used on this
connection.</p>
